“…Thus, the increase in carbon stock of sawn wood has positive impacts on climate change mitigation in addition to substitution benefits, which has also been found in previous studies [42,61,62]. This occurred in our study, although we did not consider recycling or reuse of wood products in our analysis which could have extended the lifespan of the products and benefitted the climate through carbon storing [63].…”

Abstract:The impacts of alternative forest management scenarios and harvest intensities on climate change mitigation potential of forest biomass production, utilization and economic profitability of biomass production were studied in three boreal sub-regions in Finland over a 40-year period. Ecosystem modelling and life cycle assessment tools were used to calculate the mitigation potential in substituting fossil materials and energy, expressed as the net CO 2 exchange. Currently recommended management targeting to timber production acted as a baseline management. Alternative management included maintaining 20% higher or lower stocking in forests and final felling made at lower breast height diameter than used in the baseline. In alternative management scenarios, logging residues and logging residues with coarse roots and stumps were harvested in final felling in addition to timber. The net CO 2 exchange in the southern and eastern sub-regions was higher compared to the western one due to higher net ecosystem CO 2 exchange (NEE) over the study period. Maintaining higher stocking with earlier final felling and intensified biomass harvest appeared to be the best option to increase both climate benefits and economic returns. Trade-offs between the highest net CO 2 exchange and economic profitability of biomass production existed. The use of alternative displacement factors largely affected the mitigation potential of forest biomass.

“…Many studies on the assessment of wood energy supply and demand exist from various viewpoints, for example, the supply-demand balance [21], the optimal location of an energy facility [22], such multiple aspects as environmental and socio-economic impacts [23][24][25][26], cost and environmental impacts [27,28], sustainable logistics flow [29], and resource potential and economic feasibility [30]. Cambero and Sowlati [31] reviewed studies on the assessment of forest biomass supply chains from the economic, social, and environmental perspectives.…”

“…To the best of our knowledge, no previous study has assessed wood energy from this viewpoint. In addition, most previous studies that assessed the wood energy potential first estimated the availability of wood biomass for energy as a result of logging [23][24][25][26][27][28][29][30][31][32][33][34][35] in supply-oriented studies. However, from the viewpoint of mitigating underutilization, the information required is quite the opposite; how much forest area will be maintained by implementing a new wood energy project.…”

Forest Maintenance Practices and Wood Energy Alternatives to Increase Uses of Forest Resources in a Local Initiative in Nishiwaga, Iwate, Japan

This study assesses the impact of wood energy use under underutilized conditions of wood resources: the impact on promotion of forest maintenance practices (FMPs), user costs, and local economies, using the case of a local initiative in Nishiwaga, Iwate, Japan. We conducted two main analyses: resource and economic assessment. For resource assessment, we investigate whether wood supply from FMP residue is sufficient to sustainably satisfy new demand created by a local initiative in Nishiwaga, and in how much forest area can FMPs be performed to satisfy the demand. These questions are analyzed by linear programming. Regarding economic assessment, we investigate whether replacement of fossil fuel by wood energy brings economic benefit to a user and local economy using input-output analysis. Our overall findings demonstrated that the use of wood energy under underutilized situations can lead to an increase of implementations of FMPs and of domestic wood resource supplies from a short-term perspective that comes from residues of the FMPs. We also found that wood energy consumption introduces co-benefits in terms of reduced heating costs for users and a larger economic impact on the local economy than fossil fuel.

“…In other words, using wood waste effectively produced an environmental benefit due to carbon storage of wood products. The recycling process of wood waste should be prudentially used over other uses of wood waste such landfill or energy recovery [39].…”

Evaluating the Link between Low Carbon Reductions Strategies and Its Performance in the Context of Climate Change: A Carbon Footprint of a Wood-Frame Residential Building in Quebec, Canada

Abstract:The design and study of low carbon buildings is a major concern in a modern economy due to high carbon emissions produced by buildings and its effects on climate change. Studies have investigated (CFP) Carbon Footprint of buildings, but there remains a need for a strong analysis that measure and quantify the overall degree of GHG emissions reductions and its relationship with the effect on climate change mitigation. This study evaluates the potential of reducing greenhouse gas (GHG) emissions from the building sector by evaluating the (CFP) of four hotpots approaches defined in line with commonly carbon reduction strategies, also known as mitigation strategies. CFP framework is applied to compare the (CC) climate change impact of mitigation strategies. A multi-story timber residential construction in Quebec City (Canada) was chosen as a baseline scenario. This building has been designed with the idea of being a reference of sustainable development application in the building sector. In this scenario, the production of materials and construction (assembly, waste management and transportation) were evaluated. A CFP that covers eight actions divided in four low carbon strategies, including: low carbon materials, material minimization, reuse and recycle materials and adoption of local sources and use of biofuels were evaluated. The results of this study shows that the used of prefabricated technique in buildings is an alternative to reduce the CFP of buildings in the context of Quebec. The CC decreases per m 2 floor area in baseline scenario is up to 25% than current buildings. If the benefits of low carbon strategies are included, the timber structures can generate 38% lower CC than the original baseline scenario. The investigation recommends that CO 2 eq emissions reduction in the design and implementation of residential constructions as climate change mitigation is perfectly feasible by following different working strategies. It is concluded that if the four strategies were implemented in current buildings they would have environmental benefits by reducing its CFP. The reuse wood wastes into production of particleboard has the greatest environmental benefit due to temporary carbon storage.
